Texas Instruments BQ294524 Overvoltage Protection for 2-Series and 3-Series Cell Li-Ion Batteries BQ294524DRVR

The BQ294524DRVR is a battery management IC designed for secondary-level overvoltage protection in 2-series and 3-series Li-Ion battery packs. It features independent monitoring of each cell for overvoltage conditions, with a fixed programmable delay timer that can be set to either 4 seconds or 6.5 seconds. The overvoltage protection (OVP) threshold is fixed and can be configured within a range of 3.85 V to 4.6 V, ensuring high accuracy with a tolerance of ±10 mV. The device operates with low power consumption, drawing approximately 1 µA, and has a low leakage current of less than 100 nA per cell input. The BQ294524DRVR is housed in a compact 6-pin SON package, making it suitable for applications in tablets, notebooks, power tools, and portable equipment.
